Sand Castle rocket stove.

My sand castle rocket stove. 🙂 Dirt cheap ... After watching a video of a Decota fire hole setup I saw a way to make a rocket stove to burn trash or wet wood. I love this as it allows me to make many prototypes quickly and test different designs. I use old scrap metal to keep the sand from caving in on the top and I dug a trench 10 inches wide, 2 feet deep, and about 5 foot long. From my initial test I found I need to make the hole less deep so that I can get more heat up to the top grill plate.


I was using the sand to insulate the pot....      

My next changes to this is to put the pot in direct line of the tub chamber so the hot gases have to flow around the pot to get out the chimney.      If this works well I may scale up to a 100 gal propane tank in direct line of the flow of hot gases.

Advantes of this is I can put a fan to increase burn rates without fear of burning up the chamber,  I may remove the  8 foot tall pipe and use the force air of fan to heat the pot and see how that works...

Progress.

I was able to get 3 1/2 gal of water to starting boiling in 32 min with this.

I removed the chimney and decided to use a fan for forced air.     Slowly this is getting better and better.

This was so much fun.    I need to enclose the post better, but it is working very well for me.
